The unique IP address that you want the WSDL file to be accessed from is be controlled by the Web Services Configuration option "Accept web request from IP Address". If a single IP address is entered here then only the machine that has this address may make calls to use the WSDL file. Any other machine having a different IP address will be unable to access the WSDL file and will be returned with an "IP Address Mismatch" error.

It is possible to specify a range of machines that can access the WSDL file by entering a partial IP address. Only numeric characters are allowed and the * (asterisk) wildcard character is not supported.

Example usage:

If the following is entered into "Accept web request from IP Address":

192.168

Then machines with IP addresses that begin

192.168.1.*
192.168.2.*
192.168.3.*
etc

can access the wsdl file.

If the following is entered

192.168.2

Then only machines within IP addresses beginning with this will be allowed to access the wsdl file:

192.168.2.1
192.168.2.2
etc.
